Circumstances:

The twin engine aircraft departed Tomsk Airport at 1010LT on a flight (callsign IK9007/SP5007) to Surgut, carrying 33 passengers and a crew of four. About an hour and 26 minutes into the flight, the left engine's 'chips in oil' warning light came on. About eight minutes later, a burning smell was noticed in the cockpit and the captain decided to divert to Nizhnevartovsk Airport. During the descent, the left engine caught fire. Its propeller was feathered and the crew decided to divert to Strezhevoy Airport. But as the fire could not be extinguished, the captain eventually attempted an emergency landing in the Ob River. Upon landing, the aircraft broke in two and came to rest in shallow water. Seven passengers were killed while all other occupants were rescued.

Probable cause:

The Interstate Aviation Committee (MAK) released their final report in Russian concluding the probable causes of the accident were:
The catastrophe of the AN-24 RA-47302 occurred when ditching became necessary due to a fire in the left hand engine's nacelle. The destruction of the aircraft and loss of life was caused by collision with underwater obstacles that the crew could not anticipate or avoid. The fire in the left hand engine nacelle was caused by the fracture of a centrifugal breather releasing an air-fuel emulsion into the engine compartment as well as a delayed reaction to shut the engine down by the crew following an magnetic chip detector indication together with indications of oil pressure fluctuations, a burning smell and a low oil pressure indication. A delay in indicating engine vibrations to the crew as result of degradation of the engine vibration sensoring equipment, most likely caused by changes of the rotor speed of the engine as result of the aft bearing failure of the compressor rotor and/or misalignment of the sensor, which probably influenced the decision of the crew to shut the engine down with a delay. Cause of the fracture of the centrifugal breather was the destruction of the impeller due to prolonged exposure to hot air-fuel emulsion due to the failure of the aft compressor rotor support bearing. It was not possible to determine the cause of the destruction of the aft compressor rotor support bearing due to significant secondary damage. Most likely the destruction was caused by misalignment such as:
- Incorrect assembly of support parts mating with the compressor rotor during on-condition engine repairs,
- Or deviations from required geometry of support parts mating with the compressor rotor.
Contributing factors were:
- Psychological unpreparedness of the captain to shut the engine down due to lack of experience with the aircraft on one engine inoperative
- Late detection of the fire and as a consequence late attempts to extinguish the fire, it was however not possible to establish why the fire was detected late due to lack of objective information about the performance of the fire alarm systems.

Circumstances:

Aircraft left Moscow-Domodedovo Airport in 2224LT for Petrozavodsk, Karelia. On final approach by night and fog reducing vertical visibility to 300 metres, crew descended too low without a visual contact was established with the runway lights. Aircraft descended below the MDA, hit an electric pole, crashed on a road and came to rest in a garden, 570 metres short of runway 02. Eight people were rescued as all other 44 occupants were killed. Flight was operated by RusAir on behalf of RusLine (flight 243). Russian FIFA's football referee Vladimir Pettaï was also killed in this accident. Two days later, a survivor died from his injuries. The weekend following the accident (five days and six days later), two survivors died from their injuries (burns).

Probable cause:

When the aircraft approached the airfield in weather below minimums for the aerodrome descending on autopilot at a fixed vertical speed, crew failed to decide to go around in absence of visual contact with approach lights and landmarks and permitted the aircraft to descend below minimum descent altitude, which led to impact with trees and the ground in controlled flight.
Following factors were considered as contirbutory:
- unsatisfactory crew resource management by the commander who effectively removed the first officer from the control loop in the final stages of the accident flight and who subordinated himself to the navigator showing increased activity however in the state of mild alcoholic intoxication.
- the navigator was in the state of mild alcoholic intoxication
- unjustified weather forecasts by height of cloud base, visibility and severe weather including fog as well as the non-conformity of weather data of Petrozavodsk Airport transmitted to the crew 30 and 10 minutes prior to estimated landing.
- Failure to use indications by the ADFs and other devices of the aircraft while using indications by an unapproved satellite navigation system KLN-90 in violation of flight manual supplements for the TU-134.

Circumstances:

The pilot, sole on board, was performing a crop spraying flight when the engine lost power. He elected to make an emergency landing in a field 2 kilometers from Sofyevka, in the Stavropol krai. Upon touchdown, the aircraft rolled over and came to rest upside down, bursting into flames. The pilot escaped uninjured while the aircraft was partially destroyed by fire. The wreck was evacuated and disposed away before the arrival of the accident investigation commission. Therefore, it was not possible to the MAK to determine the cause of the engine failure. As the pilot did not have any valid licence for this kind of aircraft, this PZL-Mielec AN-2R built on 11FEB1982 did not have a valid Certificate of Airworthiness. It had a double registration: FLA-34906 and RA-68122 which was the official one present in the Russian Civil Aviation registry.

Probable cause:

Engine failure in flight for undetermined reasons.

Circumstances:

Following an uneventful flight from Dniepropetrovsk, the copilot started the approach to Moscow-Sheremetyevo Airport runway 25R with the flaps down at 22°. After touchdown, he started the braking procedure but the aircraft failed to decelerate as expected. The emergency braking systems were activated without any noticeable effect. Approaching the end of the runway at a speed of 70 knots, the copilot turn to the right in an attempt to veer off runway. The airplane ground looped then contacted a grassy area and lost its undercarriage before coming to rest. All 34 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

Failure of the brakes is suspected.

The three engine aircraft was performing flight PTK123 from Petropavlovsk-Kamchatsky to Ossora. En route, the crew was informed about poor weather conditions at destination and decided to divert to the Ust-Kamchatsk Airport. Crew and passengers wait there few hours moments for weather improvement but eventually decided to return to Petropavlovsk-Kamchatsky. During the takeoff roll, the captain decided to abort for unknown reason. Unable to stop within the remaining distance (runway 01/19 is 1,725 metres long), the aircraft overran, lost its right main gear and rolled for dozen metres before coming to rest in about 50 centimeters of snow. All 26 occupants escaped uninjured while the aircraft was damaged beyond repair.

Circumstances:

The aircraft departed Voronezh-Pridacha Airport in the morning to conduct a test flight with six crew on board, two pilots from the manufacturer, two engineers and two pilots from the Myanmar Air Force to whom the aircraft should be delivered. In flight, the crew decided to perform an emergency descent. During this manoeuvre, the aircraft reached an excessive speed and lost part of its tail, stabilizers and elevators. It entered an uncontrolled descent and crashed in a snow covered field located near Garbuzovo, bursting into flames. The aircraft was totally destroyed and all six occupants were killed. Tail parts, stabilizers and elevators were later found about 3 km from the point of impact. The airplane was operated by the Voronezh Aircraft Production Association. (VASO - Voronezhskoye Aktsionernoye Samoletostroitelnoe Obshestvo). First accident involving an Antonov AN-148.

Probable cause:

The cause of the accident was the inadvertently permitted the aircraft to accelerate 110 km/h above the design limit speed during an emergency descent. This led to low-frequency vibrations on the aircraft in all axes, an increase of alternating accelerations exceeding the margin of safety. The result was the break up of the aircraft in the air, followed by its collision with the earth.
The main factors contributing to the accident were:
- Untimely and inadequate actions of the crew to control the emergency decent,
- Lack of proper coordination among the members of the crew,
- Deviations from recommendations in the flight manual in executing the emergency descent,
- Misleading indications on basic instruments when outside characteristic operating conditions.

Circumstances:

Ready for taxi, the crew started the engines when a short circuit occurred and a fire erupted in the rear compartment. The evacuation of all 134 occupants was initiated but three passengers died while 32 others were seriously injured. The aircraft was totally destroyed by fire. The OAT was -29° C at the time of the incident.

Probable cause:

A short circuit emerged while the aircraft generators were connected to the aircraft's electrical system after start-up of the engines, via an APU. The short circuit caused a strong fire in the generators compartment in the tail which spread rapidly through the fuselage. The cause of the fire was an electrical arc produced by electrical currents exceeding ten to 20 times the nominal loads when two generators not synchronized with each other were brought online but got connected together instead of being connected to parallel busses. The following contributing factors were identified:
- Poor technical conditions of contacts TKS233DOD responsible for connecting the generators with the electrical busses, that were damaged by prolonged operation without maintenance. A contact normally open was welded and fractured insulation material moved between contacts that are normally closed. These abnormal contact positions led to the connection between #2 and #3 generators.
- Differences in the schematic diagrams of generator 2 and generators 1 and 3. When the switch is moved from "check" to "enable" with no delay in the "neutral" position generator 2 is brought online without time delay which leads to increased wear of normally closed contacts in the TKS233DOD unit.
- The specific design of the electrical systems to ensure power supply to each bus from either the APU or either engine integrated drive generator.
